Optical transceiver with versatile positioning
An optical transceiver can include a transmitter and a receiver. The optical transceiver is configured to mate with an electrical connector in first and second orientations that are opposite each other. In certain examples, a thermally conductive surface of the transceiver is configured to be placed in thermal communication with a heat dissipation member in one or both of the first and second orientations. Further examples of optical transceivers can be mounted to a base and placed in electrical communication with an electrical connector. A lid provides a compressive force that simultaneously makes electrical contact between the transceiver and a host printed circuit board (PCB) and provides a low impedance heat transfer path to dissipate heat generated during transceiver operation.
1 . A transceiver comprising:
a transceiver housing defining a first side and a second side opposite the first side along a lateral direction, a first end and a second end opposite the first end along a longitudinal direction that is perpendicular to the lateral direction, and a first surface and a second surface opposite the first surface along a transverse direction that is perpendicular to each of the longitudinal direction and the lateral direction, wherein the transceiver is configured to be mated with an electrical connector in a direction defined from the second surface toward the first surface; and
a plurality of electrical contacts supported by the transceiver housing, the electrical contacts including mating ends disposed at the first side of the transceiver housing, and mating ends disposed at the second side of the transceiver housing,
wherein the transceiver includes a pocket disposed at one of the first end and the second end, the pocket configured to receive a latch of the electrical connector when the transceiver is mated with the electrical connector, thereby releasably securing the transceiver to the electrical connector.
2 . The transceiver as recited in claim 1 , wherein the pocket extends into the transceiver housing.
3 . The transceiver as recited in claim 1 , wherein the pocket is a first motion limiter element that limits motion of the transceiver in the transverse direction with respect to the electrical connector when the transceiver is mated to the electrical connector.
4 . The transceiver as recited in claim 1 , wherein the pocket does not disrupt the plurality of electrical contacts of the transceiver.
5 . The transceiver as recited in claim 1 , wherein the pocket is disposed on the second end of the transceiver.
6 . The transceiver as recited in claim 5 , wherein a cable exits from the first end of the transceiver.
7 . The transceiver as recited in claim 6 , wherein the cable is an optical fiber cable.
8 . The transceiver as recited in claim 7 , wherein the transceiver is detachably coupled to the optical fiber cable.
9 . The transceiver as recited in claim 1 , wherein the transceiver includes one optical engine that is configured as an optical transmitter.
10 . The transceiver as recited in claim 1 , wherein the transceiver includes one optical engine that is configured as an optical receiver.
11 . The transceiver as recited in claim 1 , wherein the transceiver includes one optical engine that is configured as both an optical transmitter and an optical receiver.
12 . The transceiver as recited in claim 1 , wherein the pocket is disposed at the first end, and the transceiver comprises a second pocket disposed at the second end.
13 . A communication system comprising:
the transceiver as recited in claim 1 ; and
the electrical connector.
14 . The communication system as recited in claim 13 , wherein the electrical connector is a ring connector.
15 . The communication system as recited in claim 13 , wherein a latch is disposed in the electrical connector.
16 . The communication system as recited in claim 15 , wherein the latch is configured to extend into the pocket in a latched position so as to latch the transceiver to the electrical connector.
17 . The communication system as recited in claim 15 , wherein the latch does not limit movement of the transceiver with respect to the electrical connector when the latch is in an unlatched position.
18 . A method of installing a transceiver into an electrical connector, the method comprising the steps of:
inserting the transceiver into the electrical connector in a transverse direction, wherein the transceiver comprises:
a transceiver housing defining a first side and a second side opposite the first side along a lateral direction that is perpendicular to the transverse direction, a first end and a second end opposite the first end along a longitudinal direction that is perpendicular to each of the lateral direction and the transverse direction, and a first surface and a second surface opposite the first surface along the transverse direction, wherein the transceiver housing defines a pocket disposed at one of the first end and the second end, and
a plurality of electrical contacts having mating ends disposed at the first and second sides of the transceiver housing; and
extending a motion limiter of the electrical connector into the pocket from an unlocked position to a locked position, thereby restricting motion of the transceiver relative to the electrical connector in the transverse direction.
19 . The method of installing as recited in claim 18 , wherein the extending step causes the transceiver to be latched to the electrical connector, thereby releasably securing the transceiver to the electrical connector.
20 . The method of installing as recited in claim 18 , wherein the motion limiter is in the unlocked position during the inserting step.
21 . The method of installing as recited in claim 18 , wherein after the extending step, the motion limiter is movable from the locked position to the unlocked position to allow removal of the transceiver from the electrical connector.
